Figure 7.

Sequence comparison of whole viral genomes from consecutive positive nasopharyngeal samples (subset of patients from Figure 3). Single asterisks indicate that limited read data are consistent with specified mutation (>75% of reads support variant), but position is ambiguous (N) owing to low coverage. Double asterisks indicate that limited read data provide some evidence for possible mutation or mixture (<75% of reads support variant), but position is ambiguous (N) owing to low coverage. Abbreviations: ID, identifier; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2.
